The CE 620 allows liquid mixtures to be separated by liquid-liquid extraction. The liquid mixture to be separated is supplied from the feed tank to the bottom of the extraction column using a pump. There, it moves countercurrently toward the solvent, which is supplied at the top of the extraction column by a pump. The mixture to be separated consists of a transition component and a carrier liquid. The carrier liquid and the solvent are insoluble in each other and therefore a phase boundary is established in the column. This can be observed and adjusted using two valves. The movement of the transition component from the carrier liquid to the solvent occurs within the column. Two three-way valves can be used to operate the trainer as a continuous or batch process.
